Port 2 Data Register (P2DR)
P2DR is an 8-bit readable/writable register that stores output data for the port 2 pins (P27 to P20).
P2DR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
Port 2 Register (PORT2)
Note: * Determined by state of pins P2
PORT2 is an 8-bit read-only register that shows the pin states. It cannot be written to. Writing of
output data for the port 2 pins (P2
If a port 2 read is performed while P2DDR bits are set to 1, the P2DR values are read. If a port 2
read is performed while P2DDR bits are cleared to 0, the pin states are read.
After a reset and in hardware standby mode, PORT2 contents are determined by the pin states, as
P2DDR and P2DR are initialized. PORT2 retains its prior state in software standby mode.
